That reminds me of the scene from "Robin Hood:Men in Tights". Prince John is talking to the "witch" and asking her how she came to be named "Latrine". She told him she that wasn't the name she was born with, and he says, "You changed your name TO Latrine?" She tells him, "Yeah, it used to be Sh!thouse"...
A friend of mine says they name their kids after what they see on the side of box cars.
Lol!
